5- ELECTRICAL INSTALLATION
WARNING Manufacturer recommends that this product be installed by a licensed and qualified electrician
in accordance with all applicable national, state, provincial, and local electrical codes. As with all electrical
appliances, under no circumstances should you attempt to install, repair or disassemble this water heater
without first shutting off all power to the unit directly at the fuse or breaker box.
Make sure to shut off all
breakers. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC)
in the USA, or the Canadian Electrical Code (CEC) in Canada. Failure to do so could result in property damage
and/or personal injury, and void your warranty. Note: The Canadian Electrical Code generally requires that all
supply wires and corresponding circuit protection used for domestic hot water heating and hydronic heating
applications be sized to a minimum of 125% of the maximum current rating of the heater (see heater
specifications below for details).
Before installing this product, ensure sufficient electrical power is available to handle the maximum amperage
load of the applicable heater.
IMPORTANT NOTES:
HotMax (13 kW) Recommended Wire Size:

6 AWG conductors

8 AWG ground
Manufactuer Recommends 240 VAC Single Phase

220 VAC may be used at a 15% reduction in power output

208 VAC may be used at a 20% reduction in power output
Please see electrical specifications by heater input and wiring diagram on the next page for additional
electrical information.
WARNING Hotmax must be protected by a GFCI. Connect only to a circuit that is protected by a
recognized ground-fault circuit interrupter (GFCI).
Wires must be connected to its own individual double pole breaker.
Installation Instructions
STEP 1: Make sure all electrical power is shut off. Remove the cover by
unscrewing the 1 screw on the bottom tab of the unit. Using a flathead
screwdriver, loosen the bottom two flathead screws in the white terminal
block located at the bottom right hand corner of the unit. Feed an 6 AWG
conducting wire pair through the electrical strain relief and into
Line 1 and
Line 2 of the terminal block (Figure 5). Make sure that the
breaker is connected with one red wire (Line 1) and one black
wire (Line 2) . Strip wire ends and ensure all wiring is properly
secured through the electrical strain relief located at the
bottom right when facing the unit. Tighten the two
Philipshead screws on the electrical strain relief and the two
flathead screws in the terminal block (Figure 5).
STEP 2: Using a suitable wire gauge that meets all applicable
electrical codes for the size of the breakers used, connect the 6 AWG wire pair to the correct set of wires from
the location’s main breaker panel.
